Authentication System Concept
The built-in authentication microcomputer stores the matching key data and accurately transmits the authentication results.
Security is enhanced by encrypting data transfers between the system and individual components.
Unauthorized access is prevented by the strong anti-tampering function incorporated into the authentication microcomputer.
System
Features
Uses a secure communications protocol to verify the identity of devices attempting to
establish a connection.
Strong anti-tampering function prevents unauthorized access to the authentication
microcomputer.
Fast encryption processing function supports rapid data encryption and decryption.
Built-in EEPROM non-volatile memory for storing data and programs.
Slim security IP core for a compact package.
A variety of encryption libraries (DES, 3DES, and MISTY public key encryption,
etc.) are available.
Support for the development of necessary software.
